Li-ion or Li-poly Battery?

I read somewhere on here a while ago that the Fuze has a Li-poly battery as opposed to a Li-ion Battery.  I guess it’s supposed to last considerably longer.  I’ve been trying to confirm this but can find no specific info about the battery on the Sandisk site.  I have seen on several store sights that give specs. that say it has a Li-ion battery.  I’m just wondering if anybody knows for sure and where they got that info… 

Fuze Information - link to the information on the Fuze, including the battery type

 And information on the battery at wikipedia:

That’s about all i know… from others of course (thanks!)…
